My girlfriend only initiates sex when drunk

My and my girlfriend have been living together for a while now, and I know she loves me,she adores me every day. But when it comes to sex, it only happens about once a week, and only when we’ve been drinking. When she’s sober, she never initiates, and if I do, she usually isn’t into it.

There have been times when things started but didn’t go anywhere like she lost interest or got turned off before penetration. I always make sure she’s comfortable and never push anything, but when this happens, I feel upset and don’t want to talk for a while. It’s not like I want to guilt-trip her, but it does affect me emotionally.

I don’t doubt that she loves me, but I can’t help but feel rejected. I don’t know if I should bring it up or if I’m overthinking. Has anyone else been in a similar situation? How do I navigate this without making her feel pressured or making myself feel unwanted?
